How-To: Automated incremental daily backups to Amazon S3 using Duplicity

This guide shows how to use Amazon S3 with duplicity to make secure GPG encrypted automated daily incremental backups (snapshots) of a Linux server or desktop. I have been using this method on various servers for several months and it has proved to be a reliable, secure, cheap, and robust method to create automated backups.
I have used this method on Fedora, YDL, and CentOS but the instructions should equally apply to other Linux distributions including Debian and Ubuntu. It will even work on OS X using the MacPorts version of duplicity.
